Indigenous to the Philippines, PTK-SMF™ is the authentic Pekiti-Tirsia Kali system of close-quarters combat blade fighting.

Pekiti-Tirsia is a proven system of combat strategy and tactics that provides protection from strikes and attacks, destruction of opponents weapons, and domination of any combat or self-defense situation, executed with techniques that attack, quarter, and neutralize single or multiple opponents.

The PTK-SMF standard is the use and mastery of the live blade with the proper range, timing, intent and energy of dynamic, continuous offensive and counter-offensive attacks.
